That sounds an awful lot like WoW's system, which gets abused all the time. If you provide people with a way to punish other people, they will maliciously use it. You'll also find that bots makers are very creative and will just get around your regex script by changing what they say. It's a never ending game of whack-a-mole. If you really want to stop this problem, there has only ever been one solution, to stop the demand.

I just explained how it would be difficult to abuse my solution, and if people try to abuse they're the ones who would get suspended.
